Word of the DayIntegrity(noun)
The quality of being honest and having strong moral principles; moral uprightness.
“Scientific integrity requires that researchers present the results of their experiments accurately.”
Welcome to Dr. Moore’s biology class! • Sign in!• Pick up papers from front table!• Take your seat!• Start working on your “Biology Student
Survey”

We are behind.
How are we going to get ahead?• 3-day crash course in ecology
• Levels of organization• Community interactions• Population
• Start evolution unit with other biology sections next week• Address remaining ecology content when
relevant• For example, we will address carbon and
nitrogen cycling when we learn about biological molecules
Objective
• Rank the six levels of ecological organization
By the end of class, students will be able to:
What is ECOLOGY?
ECOLOGY is the study of interactions between organisms
and their environment
Ecology is biology from the “skin out”
Six levels of ecological organization
1. Individual
2. Population: All individuals of the same species coexisting in the same place.
What is a SPECIES?
What is a SPECIES?(What makes a dog a dog?)
“I look at the term species, as one arbitrarily given for the sake of convenience to a set of individuals closely resembling each other.”
- Charles Darwin
“Species: A group whose members possess similar anatomical characteristics and have the ability to interbreed.”
- Biology, Campbell & Reece, 7th edition
Textbook definition
Population versus species• Which term generally refers to more individuals?• Under what circumstances could the terms “population” and
“species” refer to the same group?
3. Community: All populations coexisting in the same place.
4. Ecosystem: The community in a particular place plus the physical environment
4. Ecosystem: The community in a particular habitat plus the physical environment
Biotic: Having to do with the living things in an environment
Abiotic: Having to do with the non-living things in an environment
Biotic or abiotic?
Biotic or abiotic?
Biotic or abiotic?
Biotic or abiotic?
Can the abiotic characteristics of an ecosystem affect the biotic characteristics?
Can the biotic characteristics of an ecosystem affect the abiotic characteristics?
5. Biome: All ecosystems with similar characteristics
6. Biosphere: All regions of earth inhabited by life
Six levels of ecological organization
Which level of ecological organization is shown in the image?
Which level of ecological organization is shown in the image?
Which level of ecological organization is shown in the image?
Which level of ecological organization is shown in the image?
Are members of the same population always members of the same community?
Terms are just tools!
Homework (20-point homework grade)• “Ecological Levels of Organization” worksheet• Due next class meeting!
Exit ticket (10-point classwork grade)• Compare and contrast a SPECIES versus a POPULATION• How are the terms the same?• How are the terms different?• Which term generally refers to more individuals?• Could the terms ever refer to the same group of individuals? If so, under what
conditions?
